How to find file last modification date?

Heloo all I have some mat files that contains some numbers. and I have variable x that contains the one of this mat file name. now I want to figure out the last modification date of this mat file through x variable input. I tried to do this in such a way but failed.

file=dir('x{1,1}.mat')
file.date

Any idea would be a great job for me.

Thanks in edvance
